https://externalassets.unilogcorp.com/ASSETS/DOCUMENTS/ITEMS/EN/Armstrong_Air_17A91_Catalog.pdf- 93% AFUE Efficiency Rating - This means 93% of your fuel is converted into usable heat. Compared to an older furnace, this can potentially save you hundreds of dollars per year in energy costs
- Constant Torque Motor - Like a variable speed air handlers, constant torque air handlers provide lower operating costs and increase overall system efficiency. Compared to standard PSC motors, constant torque delivers more consistent airflow and quieter operation
- Quiet Combustion™ Technology - Uses a smaller Btu input per burner for quieter start-up and operation while providing more even heat distribution
- EHX™ Technology - Every Armstrong Air furnace is engineered and built with EHX Technology, a patented design that eliminates the hot spots that can shorten furnace life. EHX Technology makes heat exchangers more durable, and with its advanced airflow system, more air contacts the heat exchanger surface area for greater heat exchange, enhancing efficiency and comfort
